To aZZ whom it may concern-.-

Be it known that I, DANIEL S. REGAN, a citizen of the United States, and aresident of the city and county of San Francisco, and State of California, have invented certain new and useful Improvements in Governors for Gas- Engines, of which the following is a specification.

My invention relates to governors for gas- 10 engines.

Figure 1 is a side elevation of the governor, showing its attachment to the main shaft, which is shown broken off; Fig. 2, an inside view of the same, showing the operating-gear;

Fig. 3, an outside view showing the position of the crank and piston of the engine and the end of the shaft, with the position of the gear denoted by dot-ted lines.

The following is the construction of my improved govern or I form the sleeve and inside gear, A,'and the wheels gearing with the same of metal and finish the same smoothly, as that class of machinery is generally finished. I attach. the cams B and 0 upon the periphery of the wheel A, for the purpose of operating the valve-levers D and E to open and close the valves. F represents the inside spur gear or teeth of the wheel A. The main spur-wheel upon the crank-shat t S is represented by the letter G, and the intermediate gear by the letterl-I. l attach the collar l, which contains thehingoarms .l and la, firmly to the main shaft. 1 attach the governor-balls L and M ai'nlplcvers O and l, by pivot ing them.

Attached to the gear-wheel A is the groovi-a'i collar Q, by means of which groove the governor-levers and 1, connect for the purpose of movin the gear-wheel A in and out suliiciently to connect and disconnect the cams with the lever E. 1 construct the gear 1" suiliciently wide to allow the req u i red sliding upon the intermediate wheel, ll, and allowing the connecting and disconnecting of the cam and the lever E, as will be more fully explained by the operation of the same.

The action of the governor-balls is similar to those of other ball-governors.

It will be seen that the wheelA, with cams B and C, and eonnecting-collarQ, with groove R, are allowed to slide out and in upon the shaft to and to revolve independently of the movement of the same.

T represents the piston, and U the pitnian or connecting od of the engine; V, the cylinder.

X and Y represent the anti-frietion rolls of the valve-levers.

The following is the operation of my improved governor: It will be seen that the 0bj ect is to secure the action of both the exhaust and supply valve once in two revolutions, and to that end the operating-gear F, G, and H are so proportioned that the wheel A is made to revolve once while the wheel G and shaft S make two revolutions. As the main or crank shaft S is revolved, the piston is moved out and in the cylinder. The first outward stroke fills the cylinder from any suitable gas and air supply, as other engines are supplied with a charge of gas and air by suitable con.- necting-pipes and CllGClGYZtlYOS. As the crank continues to revolve and the piston is forced in, compressing the gas, the electric spark or other igniting heat is produced and the '7 5 charge ignited, and the piston is forced out, expending itsforce upon the crank of the engine. The crank ccmtiuuing to revolve, the

I cam 13 having reached. the exhaust-lever D,

the exhaust is 0])(110k'l and held open until the piston has reached the on d of the back-stroke and the exhaust is completed, the cam B having then passed the end of the lever D, and the exhaushvalve again closes. The supplyvalve is then opened as the cam. 0 comes in contact, with the lever E, and remains open until the outward stroke of the piston is made and one-fourth revolution of the wheel A is made. The cylinder is new full, and as the piston passes back the charge is compressed and ignited and the piston. forced out, as before, giving its force to the crank of the engine. It will be seen that the cams B and 0 each occupy one-fourth of the circumference of the wh eel A,which corresponds to the time taken for one half-stroke of the piston, thus securing two revolutions to each action of the supply and exhaust valves.

The action of the governor is as follows: As the speed of the shaft is accelerated, the balls L and M are thrown out and the lever-armsO and P draw the wheel A out, and the cam G lever E then has a hearing the whole eireumcombination With the Valve-levers D and E, iferenoe of the Wheel A, thus on'litting' the opeonstructed and operated substantially as and eration of the supply-valve until the speed of for the purposes set forth. 5 the engine is brought down, to what is required.
